​How many free allowances are allocated to each operator?

On 26 September 2011, the European Commission published the benchmark values which would be used to allocate greenhouse gas emission allowances free of charge to more than 900 aircraft operators.

Publication of the benchmark values enables operators to calculate their free allocation of allowances up to 2020. One benchmark has been calculated for the 2012 trading period and another for the 2013-2020 trading period:

In 2012, each operator will receive 0.0006797 allowances for free for each tonne-kilometre

Between 2013 and 2020, each operator will receive 0.0006422 allowances for free for each tonne-kilometre each year

If we call "TK 2010" your reported TK data in 2010, this means that you will receive [0.0006797 * TK 2010] allowances for free in 2012, and [0.0006422 * TK 2010] allowances for free each year between 2013 and 2020.
